Vim <strong>101</strong> Hacks<br />
www.thegeekstuff.com<br />
• n – Will not replace the current highlighted word. But it will<br />
automatically highlight the next word that matched the search<br />
pattern<br />
• a – Will substitute all of the remaining matches without further<br />
prompting.<br />
• l – This will replace only the current highlighted word and terminate<br />
the find and replace effort.<br />
Example 9. Prepending every line with its line number<br />
When the replacement string starts with ‘\=’, it should be evaluated as an<br />
expression. Using the ‘line’ function we can get the current line number.<br />
:%s/^/\=line(".") . ". "/g<br />
Note: This is different from “:set number” which does not write the line<br />
numbers into the file. When you use this substitution you are making these<br />
line numbers part of the actual content of the file.<br />
Example 10. Substituting a special character with an equivalent<br />
value.<br />
Substituting the ~ character with the value of the $HOME variable.<br />
Original Text: Current file path is ~/test/<br />
:%s!\~!\= expand($HOME)!g<br />
Translated Text: Current file path is<br />
/home/ramesh/test/<br />
Notes:<br />
• You can use the expand function to expand any available predefined<br />
or user defined variables.<br />
